RDMA/qedr: Dispatch port active event from qedr_add

2017-01-24T20:35:08+00:00

Relying on qede to trigger qedr on startup is problematic. When probing
both if qedr loads slowly then qede can assume qedr is missing and not
trigger it. This patch adds a triggering from qedr and protects against
a race via an atomic bit.

mark qedr_get_state_from_ibqp(), __qedr_alloc_mr() and __qedr_post_send()
as static since they are only used in the same file.

Fail QP state transition from error to reset if SQ/RQ are not empty
and still in the process of flushing out the queued work entries.

RDMA/qedr: Don't spam dmesg if QP is in error state

2017-01-24T20:34:54+00:00

It is normal to flush CQEs if the QP is in error state. Hence there's no
use in printing a message per CQE to dmesg.

RDMA/qedr: Remove CQ spinlock from CM completion handlers

2017-01-24T20:34:43+00:00

There is only a single event queue that triggers the completion
events for the RDMA CM and it is being processed serially. This means
that inherently there can no parallelism of CQ completion handler
callbacks, hence the lock is redundant.
